This study investigated how stroke patients improve the walking patterns by using the Elastic Walking Band, which was included with a long elastic band and four pierced plastics as fixed points. Fifteen patients with stroke were recruited. Participants were nine males and six females. Gait parameters were measured with the GAITRite system to analyze the spatial and temporal parameters of walking by stroke patients. The Elastic Walking Band had no significance in cadence, swing time and stance on both limbs. However, the Elastic Walking Band significantly improved velocity in stroke patients. Furthermore, there was a significant difference in step length of the less-affected limb between the two conditions, but no significant difference in the affected side. When the patients walked with the Elastic Walking Band, affected and less-affected stride length were also significantly increased as compared with barefoot walking. There were significant differences of velocity, less-affected step length, both stride length between walking with and without the Elastic Walking Band. Consequently, the Elastic Walking Band can be used as an assistive walking device that is lighter and less expensive for stroke patient gait training in the clinic.
